Description

The present invention relates to a marking film laminate and a clothing marking film in which a printed layer is formed on the marking film laminate.

In clothing items such as T-shirts and trainers, it is common practice to display and decorate predetermined characters and designs.
As a method for decorating clothing, a single-color marking film is cut and then attached to the clothing, and characters and designs are displayed by the color of the marking film itself. Is printed on a marking film, the printed marking film is cut, and then affixed to clothing.
In particular, recently, there is a high demand for the latter method because multicolor display can be easily performed, and a printable marking film for clothing is required.

On the other hand, what consists of vinyl chloride resin is known as a base material which comprises the product generally called a marking film (it is not limited to clothing use) (for example, refer patent document 1, 2). However, when a character or design is applied by printing on a marking film having a substrate made of a vinyl chloride resin, the ink absorbency is poor and the printability (coloring property) during printing is poor. Further, color fading may occur during washing or dry cleaning, and the marking film may be peeled off or damaged. Furthermore, the marking film for clothing may be stretched at the time of use due to the movement of the human body, but the restoring property at that time has not been sufficiently ensured conventionally.

JP-A-6-322205 JP-A-7-126465

As described above, when a marking film provided with a base material made of a conventional vinyl chloride resin is used as a marking film for clothing, the printing property, washing resistance and dry cleaning resistance, and washing and dry cleaning are not possible. It was not satisfactory in terms of color fading and stretch / restorability.

Accordingly, the present inventors have made extensive studies to solve the above problems, and as a result, a marking comprising a base material made of a vinyl chloride resin composition and an adhesive layer laminated on one side of the base material. In a laminate for film, as a vinyl chloride resin composition, by using a vinyl chloride resin composition containing a specific polyvinyl chloride resin and a specific plasticizer in a predetermined amount, printability and stretch / restorability can be improved. The present invention has been completed by finding that it is a laminate for a marking film that is excellent and does not cause discoloration or texture deterioration during washing or dry cleaning.

The marking film laminate of the present invention is a marking film laminate comprising a substrate made of a vinyl chloride resin composition and an adhesive layer laminated on one side of the substrate,
The vinyl chloride resin composition includes a polyvinyl chloride resin having an average degree of polymerization of 1000 to 1500, and a polyester plasticizer having a molecular weight of 1000 to 3000.
The blending amount of the polyester plasticizer is 30 to 60 parts by weight with respect to 100 parts by weight of the polyvinyl chloride resin.
It is used for a marking film for clothing printed using a solvent-based pigment ink.

In the laminate for marking film of the present invention, the adhesive layer is preferably made of a hot melt adhesive having a softening temperature of 100 to 160 ° C.

The marking film laminate of the present invention preferably includes a separator layer laminated on the side opposite to the substrate side of the adhesive layer.

In the marking film for clothing of the present invention, a printed layer printed using a solvent-based pigment ink is formed on the surface opposite to the adhesive layer side of the substrate of the laminate for marking film of the present invention. Features.

In the marking film for clothing of the present invention, the printing is preferably inkjet printing.

Since the laminate for marking film of the present invention includes a base material composed of a vinyl chloride resin composition having a specific composition, it has excellent stretch recovery properties and printability, and forms a printing layer using a solvent-based pigment ink. In this case, it is possible to provide a marking film that does not lose color during washing and dry cleaning, and does not peel or break the film and does not deteriorate the texture (excellent in washing resistance and dry cleaning resistance). It is a laminate for a marking film which is extremely suitable for a marking film for clothing used by being attached to a product.
In addition, the marking film for clothing of the present invention has a printed layer printed using the solvent-based pigment ink on the laminate for marking film of the present invention. Very suitable.
In the present invention, washing means washing clothes using water (or hot water) as a solvent, and dry cleaning means washing clothes using a petroleum solvent or a chlorine solvent as a solvent. .

FIG. 1 is a cross-sectional view schematically showing an example of the marking film laminate of the present invention. FIG. 2 is a cross-sectional view schematically showing an example of a marking film for clothing of the present invention. FIG. 3 is a color sample for evaluating the degree of color fading during washing and dry cleaning.

Hereinafter, first, the laminate for a marking film of the present invention will be described with reference to the drawings.
The marking film laminate of the present invention is a marking film laminate comprising a substrate made of a vinyl chloride resin composition and an adhesive layer laminated on one side of the substrate,
The vinyl chloride resin composition includes a polyvinyl chloride resin having an average degree of polymerization of 1000 to 1500, and a polyester plasticizer having a molecular weight of 1000 to 3000.
The blending amount of the polyester plasticizer is 30 to 60 parts by weight with respect to 100 parts by weight of the polyvinyl chloride resin.
It is used for a marking film for clothing printed using a solvent-based pigment ink.

FIG. 1 is a cross-sectional view schematically showing an example of the marking film laminate of the present invention.
As in the example shown in FIG. 1, in the marking film laminate 10, an adhesive layer 12 is laminated on one side of a base material 11 made of a vinyl chloride resin composition, and the base material 11 of the adhesive layer 12 is further laminated. A separator layer 13 is laminated on the opposite side.
Here, the vinyl chloride resin composition constituting the substrate 11 contains at least a polyvinyl chloride resin and a polyester plasticizer.

The polyvinyl chloride resin has an average degree of polymerization of 1000 to 1500.
When the average degree of polymerization of the polyvinyl chloride resin is less than 1000, the stretching / restoring property of the marking film laminate is insufficient. On the other hand, the laminate for marking film of the present invention usually forms a printed layer and then cuts it to make a marking film for clothing. When the average degree of polymerization of the polyvinyl chloride resin exceeds 1500, Cutting performance is greatly reduced.

In this specification, the average degree of polymerization of a polyvinyl chloride resin means the average degree of polymerization measured based on JIS K 6721 “Testing method of vinyl chloride resin”.
Examples of the polyvinyl chloride resin include homopolymers of vinyl chloride, copolymers of vinyl chloride and other monomers copolymerizable therewith.
Examples of the other copolymerizable monomers include vinyl esters such as vinyl acetate and vinyl propionate, olefins such as ethylene, propylene, and styrene, methyl acrylate, ethyl acrylate, and methyl methacrylate. ) Acrylic acid esters, maleic acid diesters such as dibutyl maleate and diethyl maleate, fumaric acid diesters such as dibutyl fumarate and diethyl fumarate, vinyl cyanide such as acrylonitrile and methacrylonitrile, vinylidene chloride and vinyl bromide And vinyl ethers such as vinyl halide, methyl vinyl ether, and ethyl vinyl ether. These may be used alone or in combination of two or more.
The content of the other copolymerizable monomer in the copolymer is usually 50% by weight or less, preferably 10% by weight or less.

The polyester plasticizer has a molecular weight of 1000 to 3000.
If the molecular weight of the polyester plasticizer is less than 1000, it will be difficult to restore once stretched, resulting in poor stretch resilience. When washing and dry cleaning, the marking film for clothing may be peeled off, damaged, or discolored. Will be. Moreover, at the time of dry cleaning, a polyester plasticizer may elute, and the softness | flexibility of the marking film for clothes may fall.
On the other hand, when the molecular weight of the polyester-based plasticizer exceeds 3000, it is difficult to stretch in the first place, so that the stretch recovery property is poor, and since the plasticizing efficiency is low, the flexibility and fluidity are inferior, and the workability is deteriorated. Moreover, the printability at the time of printing will also fall.

In this specification, the molecular weight of a polyester plasticizer is a number average molecular weight, and is a measured value in terms of polystyrene by GPC (gel permeation chromatograph) measurement.
The GPC measurement method is performed according to a standard method. A dilute tetrahydrofuran solution of the polyester plasticizer to be measured is prepared and measured using a GPC measuring device “HLC-8220GPC” manufactured by Tosoh Corporation under a flow rate condition of 0.6 ml / min. As the column, “KF606M” and “KF603” manufactured by Showa Denko KK were used.

The polyester plasticizer is not particularly limited as long as it is compatible with the polyvinyl chloride resin. For example, polyalkylene glycol such as polyethylene glycol diester, polypropylene glycol diester, and polyethylene glycol polypropylene glycol diester of phthalic acid. Examples thereof include polyethylene glycol diesters of aliphatic dibasic acids such as diesters, adipic acid, and sebacic acid, polyalkylene glycol diesters such as polypropylene glycol diester, and polyethylene glycol polypropylene glycol diester.
Among them, it is preferable to use a polyalkylene glycol diester of an aliphatic dibasic acid from the viewpoint that excellent printability, adhesive properties, and dimensional stability are obtained, and it is particularly preferable to use a polyalkylene glycol diester of adipic acid. preferable. These polyester plasticizers may be used alone or in combination of two or more.

The amount of the polyester plasticizer is 30 to 60 parts by weight with respect to 100 parts by weight of the polyvinyl chloride resin.
If the said compounding quantity is less than 30 weight part, while the shrinking | restoration restoring property of the laminated body for marking films will fall, the printability at the time of printing will fall. Also, the flexibility is inferior. On the other hand, when the blending amount exceeds 60 parts by weight, the marking film for clothing is peeled off or damaged during washing, or the color fading tends to occur during washing and dry cleaning. Moreover, it will be inferior to the printability at the time of printing. Furthermore, since it becomes difficult to restore once stretched, it is also inferior in stretch recovery property.

The vinyl chloride resin composition preferably further contains a stabilizer.
Examples of the stabilizer include metal soaps such as fatty acid calcium, fatty acid zinc, and fatty acid barium, hydrotalcite, β-diketone compound, a copolymer of glycidyl methacrylate and methyl methacrylate (for example, manufactured by NOF Corporation: Far Pack 50MP). Examples of the fatty acid component of the metal soap include calcium laurate, calcium stearate, calcium ricinoleate, zinc laurate, zinc ricinoleate, zinc stearate, barium laurate, barium stearate, and barium ricinoleate. it can. In addition, as the stabilizer, epoxy stabilizer, barium stabilizer, calcium stabilizer, tin stabilizer, zinc stabilizer, calcium-zinc (Ca-Zn), barium-zinc (Ba) Composite stabilizers such as —Zn-based ”can also be used.
These stabilizers may be used alone or in combination of two or more.
The stabilizer is preferably a powdery stabilizer rather than a liquid stabilizer. This is because it does not easily dissolve during washing or dry cleaning. In addition, the liquid stabilizer may bleed and inhibit printability during printing.

Moreover, the blending amount of the stabilizer is preferably 0.5 to 5 parts by weight with respect to 100 parts by weight of the polyvinyl chloride resin.
If the amount is less than 0.5 part by weight, the effect as a heat stabilizer may not be fully enjoyed, and if the amount exceeds 5 parts by weight, the plate may be out during processing.

The vinyl chloride resin composition may be blended with a colorant generally used for polyvinyl chloride resin, if necessary.
Examples of the colorant include titanium oxide, zinc oxide, carbon black, nigrosine dye, aniline blue, carlo oil blue, chrome yellow, ultramarine blue, dupont oil red, quinoline yellow, methylene blue chloride, phthalocyanine blue, and malachite green oxa. Rate, a mixture thereof, and the like.
By blending the above, a colored marking film laminate is obtained.

The vinyl chloride resin composition may be blended with additives such as lubricants, modifiers, fillers, diluents, foaming agents and the like that are generally used for polyvinyl chloride resins, if necessary. .

Although the thickness of the said base material is not specifically limited, 50-100 micrometers is preferable.
When the thickness of the substrate is less than 50 μm, the substrate is not stiff and workability may be deteriorated. Further, the ink absorbability is low, and the printability during printing may be inferior.
On the other hand, if the thickness of the substrate exceeds 100 μm, the flexibility of the substrate is insufficient, and the marking film may become stiff when pasted on clothing.

The adhesive constituting the adhesive layer 12 is not particularly limited, and an adhesive conventionally used in the field of marking film can be used. Even if it is a solvent type, an emulsion type, a hot melt type, etc. Although a solventless type may be used, a hot melt adhesive is preferred.
As will be described later, the laminate for a marking film of the present invention, after forming a printed layer on a base material, is attached to a clothing article through the steps of cutting and thermocompression bonding, these steps, This is because a hot melt adhesive is particularly suitable for performing the cutting process.

The hot melt adhesive is not particularly limited as long as it can adhere to clothing, and examples thereof include thermoplastic polyurethane, styrene / isoprene block copolymer, styrene / butadiene block copolymer, and styrene / ethylene. / Butylene block copolymer, ethylene / vinyl acetate thermoplastic elastomer and the like.
The hot melt adhesive preferably has a softening temperature of 100 to 160 ° C.
If the softening temperature of the hot melt adhesive is less than 100 ° C, peeling or stickiness may occur during use. On the other hand, if it exceeds 160 ° C, the temperature of thermocompression bonding needs to be 160 ° C or higher. This is because the substrate and the printed layer may be thermally deteriorated.
Moreover, the said adhesive agent may contain the various additives (A stabilizer, a plasticizer, a softener, dye, a pigment, etc.) normally mix | blended with an adhesive agent.

Although the thickness of the said adhesive bond layer is not specifically limited, 20-60 micrometers is preferable.
If the thickness of the adhesive layer is less than 20 μm, the adhesive strength may be insufficient. On the other hand, if the thickness exceeds 60 μm, the clothing marking film may become stiff when it is applied to clothing, which is also disadvantageous economically.

Although it does not specifically limit as said separator layer 13, Although a conventionally well-known thing can be used, Films, such as a polypropylene processed with the silicone resin, etc. can be used suitably from an environmental viewpoint.
In addition, the said separator layer does not necessarily need to be laminated | stacked in the laminated body for marking films of this invention.

The marking film laminate preferably has a weight reduction rate of 10% by weight or less when immersed in hexane. When the weight phenomenon rate is 10% by weight or less, in the clothing marking film using the marking film laminate, discoloration during washing and dry cleaning can be avoided. In addition, when the above-mentioned reduction rate of receipt is 10% by weight or less, the printability at the time of printing is excellent, whereas when it exceeds 10% by weight, the printability deteriorates with time, and printing after storage for a long time May be inferior.
In the laminate for marking film of the present invention, the weight reduction rate when immersed in hexane is a value measured using the following method.
That is, the marking film laminate whose weight was measured in advance was immersed in hexane, allowed to stand at 40 ° C. for 12 hours, then taken out, dried at 60 ° C. for 12 hours, and then the weight of the marking film laminate was measured. It is the value which measured and calculated the ratio of the reduction | decrease weight with respect to the weight before immersion as a percentage.

The marking film laminate preferably has a 50% modulus of 10 N / 10 mm or more.
This is because when the 50% modulus is in the above range, the stretchable restoration property of the marking film laminate tends to be more excellent. The 50% modulus is measured according to JIS K 6732.
In addition, when the said laminated body for marking films is equipped with a separator layer, the weight reduction rate at the time of the said hexane immersion and the said 50% modulus are measured in the state which peeled the said separator layer.

Next, the manufacturing method of the laminated body for marking films of this invention is demonstrated.
(1) First, a base material is produced. Specifically, the vinyl chloride resin composition is obtained by melt-kneading the constituent components of the base material including the polyvinyl chloride resin and the polyester plasticizer with each predetermined amount using a continuous kneader, a Banbury mixer, a kneader, an extruder, and the like. Then, this vinyl chloride resin composition is produced by forming a film by calendar molding, extrusion molding, injection molding or the like.
Here, it is preferable to form a film by calendering. It is easy to make the thickness of the base material uniform, can be formed regardless of the composition of the vinyl chloride resin composition, and is also suitable for forming base materials of various sizes such as larger sizes. This is because it is easy to handle small lots.
Examples of the calendar format used for the calendar molding include an inverted L shape, a Z shape, an upright two shape, an L shape, and an inclined three shape.
Moreover, the roll temperature at the time of calender molding may be appropriately selected according to the composition of the vinyl chloride resin composition, but is usually 140 to 190 ° C, preferably 160 to 180 ° C.

(2) Next, an adhesive layer is formed on one side of the substrate.
The adhesive layer may be formed by a conventionally known method. The adhesive layer may be applied directly to a substrate using a bar coater or the like, dried, or once applied to a separately prepared support. After drying, it may be transferred and formed. Further, when a release paper is used as the support, a separator layer can be formed at the same time as the adhesive layer is formed.
By such a method, the marking film laminate of the present invention can be produced.

The marking film laminate of the present invention having such a structure is a clothing marking film that is extremely suitable for application to a clothing article by applying a printing layer by printing using a solvent-based pigment ink. It can be.

Next, the clothing marking film of the present invention will be described with reference to the drawings.
In the marking film for clothing of the present invention, a printed layer printed using a solvent-based pigment ink is formed on the surface opposite to the adhesive layer side of the substrate of the laminate for marking film of the present invention. Features.

FIG. 2 is a cross-sectional view schematically showing an example of a marking film for clothing of the present invention.
Like the example shown in FIG. 2, the marking film 20 for clothes is the adhesive of the base material 11 of the laminated body for marking films of this invention by which the base material 11, the adhesive bond layer 12, and the separator layer 13 were laminated | stacked in this order. A printed layer 14 printed using a solvent-based pigment ink is formed on the surface opposite to the layer side 12.

In the marking film for clothing of the present invention, it is extremely important that the printing layer 14 is formed using a solvent-based pigment ink.
The base material composed of the vinyl chloride resin composition having the specific composition described above is excellent in adhesion with solvent-based pigment ink, in particular, adhesion with vehicle of solvent-based pigment ink. This is because discoloration does not occur.

As the solvent-based pigment ink, a conventionally known solvent-based pigment ink mainly composed of a solvent, a pigment, a vehicle, and an auxiliary agent blended as necessary can be used. -Vinyl-based resins such as vinyl acetate copolymer resins, acrylic-vinyl acetate copolymer resins, and solvent-based pigment inks containing acrylic resins are used for adhesion to the substrate constituting the marking film laminate. It is preferable at an excellent point.

Examples of the solvent include glycol ether solvents such as diethylene glycol diethyl ether, tetraethylene glycol dimethyl ether, and tetraethylene glycol monobutyl ether, lactone solvents such as γ-butyrolactone, low boiling aromatic naphtha, and propylene glycol monomethyl ether acetate. Can be mentioned.
Examples of the pigment include carbon black (black), copper phthalocyanine (cyan), dimethylquinacridone (magenta), pigment yellow (yellow), titanium oxide, aluminum oxide, zirconium oxide, and nickel compounds. Are known and are not limited to the above.

Specific examples of such solvent-based pigment inks include, for example, SS21 ink, ES3 ink (both manufactured by MIMAKI), Eco Sol MAX (manufactured by ROLAND), and the like.

The marking film for clothing of the present invention can be produced by forming the printed layer on the laminate for marking film of the present invention.
The printing layer can be formed using a conventionally known printing method using the solvent-based pigment ink, for example, ink jet printing, screen printing, offset printing, gravure printing, and the like. Among these printing methods, inkjet printing is preferable. This is because it is easy to handle multi-product and small-lot production.
Although the inkjet apparatus used by the said inkjet printing is not specifically limited, For example, CJV-30, TPC-1000 (both made by Mimaki), XC-540, SP-300 (both made by Rolland) etc. are mentioned.
